Technical speedway steering box adapter

i got the speedway sagniaw gear box adapter plate for my 47 ford this year for christmas, i tried putting it in today and none of the slotted holes lined up with the plate i figure they were about 1/8" off. anyone have the same experience? Is it different for a 41?

 

If I remember correctly 41 is different from 47.

years back did install of Vega box on '47 Coupe - had to buy three different brands to find one that almost fit- 3rd one needed to have part heated and bent to line up right -

 

I've got an extra I'll see how that fits

Good luck on your project.

 

I used a Weedeter 525 box mount on my '47; it replaced the Ford mount. I had a Pete & Jakes adapter plate; but I decided I wanted the little extra room that Weedeter's mount provided.

I seem to remember that a couple of the holes in the original Ford frame mount had to be slotted to fit the adapter plate.

 

So I figured it out. The holes in the frame plate were smaller than the holes/hardware on the adapter plate. So with a sacrificial drill bit is was able to open the holes enough to get it a tight fit
